Relay Module 1 2 4 8 Channel 12V Board Shield with Optocoupler Support High and Low Level Trigger for(8 Channel 12v)

relayRelay module 1 2 4 8 Channel 12V Relay Module Board Shield with Optocoupler Support High and Low Level Trigger for Description:1, the module uses genuine high-quality relay, the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A;2, using patch optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;3, the module working voltage is available in 5V, 12V, 24V;4. The module can be triggered by a jumper to set a high level or a low level;5, fault-tolerant design, even if the control line is broken, the relay will not move;6, power indicator (green), relay status indicator (red)7, the interface design is user-friendly, all interfaces can be directly connected through the terminal block, very convenient8, module size: 50mm * 26mm * 18.5mm (length * width * height)9, with 4 fixing bolt holes, hole 3.1mm, spacing 44.5mm*20.5mmTwo module interface:1. DC+: Connect the positive pole of the power supply (the voltage is selected according to the relay, and there are 5V, 12V and 24V options)2, DC-: connected to the negative pole of the power supply3, IN: can control the relay to pull high or lowRelay output:1. NO: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction.2, COM: relay common interface3. NC: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.High and low trigger selection:1. When the jumper is shorted to LOW, it is triggered by low level;2. When the jumper is shorted to high, it is triggered by a high level.Third, technical parameters:Relay version Quiescent current Maximum current Trigger current Trigger voltage (low) High5V 5mA 190mA 2-4mA 0-1.5V 2.5-5V12V 5mA 80mA 2-4mA 0-4V 4.5-12V24V 5mA 50mA 2-4mA 0-8V 8.5-24V
